Get an LS and a supercharger. You will need a matching xmission too.

I very seriously doubt that an AW4 orAX15 will tolerate a 700hp motor without exploding. A stock 4.0 block won't either.

or just throw in a stroked, boosted v8 and it would probably be a bit cheaper...

You plan on doing a ground up tube frame custom build with a SB of some kind in it? 700hp NA in a SBC is easy to do just takes some good parts, the SBF's I don't about them as I have always built SB chevy engines in recent years.

Am I seeing both a turbo and a supercharger on a 4.0? That is just ridiculous...

Nissan Patrol with the RB30 6 cylinder turbocharged
Is that your class and the competition?

Obviously there are 'Class' restrictions.

505 did 5.0L stroker and 19 pounds boost and made 692 HP and 777 TQ.
With turbo, intercooler, meth injection, 118 octane race fuel, maxed out 48 pound injectors with higher fuel pressure.

I don't see many intakes with pulleys on them unless they are superchargers. Am I mistaken and that pulley on the intake is a P/S pump?


I sure wish I had the $ to put a $15,000 motor in my Jeep so I can blow it up going over a hill to impress my drunk friends at the bottom.
